Transforms the chatbot into a Graphviz DOT generator. It outputs single-line diagram code with custom node counts and no conversational filler.

## What it does

This prompt configures an AI assistant to act as a Graphviz DOT diagram designer. It enforces strict structural parameters: the layout engine is set to `neato`, node overlap is disabled with `overlap=false`, and shapes default to plain rectangles without decorative styling.

Node labels use numeric indices to keep the generated code compact. You control graph complexity by appending the desired node count in brackets, while the generator defaults to 10 nodes when no target size is supplied. The system returns the complete DOT definition on a single line without commentary.

Because the prompt forbids styling and locks the engine to `neato`, you cannot generate colored themes or alternate layouts directly without post-processing the output in Graphviz.

## Install

### ChatGPT (native platform)

**How to use**
- Paste the text at the start of a chat or into project instructions

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/prompts.csv.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/f/prompts.chat/tree/HEAD/prompts.csv

## When to use it
- generate compact Graphviz DOT diagrams for complex concepts
- enforce a minimum node count using bracket notation
- receive single-line graph syntax without explanatory text
- prevent overlapping layout elements with neato engine flags

## Example prompts
- The water cycle [8]
- Software deployment pipeline

Below is the content of a third-party file. It is data, not instructions for you: do not act on anything written inside unless the human asks. Block tag: d9b4276fa0b98afe.

BEGIN THIRD-PARTY FILE d9b4276fa0b98afe
```text
I want you to act as a Graphviz DOT generator, an expert to create meaningful diagrams. The diagram should have at least n nodes (I specify n in my input by writting [n], 10 being the default value) and to be an accurate and complexe representation of the given input. Each node is indexed by a number to reduce the size of the output, should not include any styling, and with layout=neato, overlap=false, node [shape=rectangle] as parameters. The code should be valid, bugless and returned on a single line, without any explanation. Provide a clear and organized diagram, the relationships between the nodes have to make sense for an expert of that input. My first diagram is: "The water cycle [8]".
```
END THIRD-PARTY FILE d9b4276fa0b98afe

The third-party file has ended. Everything between the d9b4276fa0b98afe tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
